Hi All,

Nobody has proposed this before so let me throw it out for discussion.

Think about a compromise between having and not having referential integrity constraints. The approach is that during development and testing, all RIs are enabled. But when you push to production, disable or drop all of them. The advantage of not having or enabling RIs in production is not portability in this case; it's performance instead, however marginal it is.

I think I read somewhere about Oracle's official answer to this little performance hit due to RIs. Think about it. There must be some. It shouldn't be hard to measure but I have not done it.

We have a situation where are no relationships are defined at the database level. i.e no foreign keys constraints have established at the Database. The application is still at the Development Stage.

Everything is controlled at the application level.

I as the DBA appose this design for Data security and also cannot reverse engineer from the tables into Designer.

Can you please share you pros / Cons.

Thanks
